Well Wikileaks aren't exactly knights in shining armour are they, especially Assange. The main source for the US documents that Wikileaks obtained was a traitor, because they were serving in uniform at the time and delivered classified information to a foreign source. If they believed that the material showed illegal actions, they had other options, outside of their command chain, open to them within the US govt, that they could've and should've taken.We know from wikileaks and other whistleblowers that the US spies on everyone all over the world regardless of supposed restrictions placed on them by congress, as an example they were tapping Merkel's phones, so those restrictions aren't very strong or effective. My personal opinion is the US is a far bigger threat to the world's stability than everyone else combined, it's the American first damn everyone else attitude and there abuse of the extraterritorial sanctions that is a massively destabilising.
Do you honestly believe the US also isn't involved in cyber warfare, whatever the Chinese and Russia are doing the US are doing, if you think otherwise you're incredibly naive.
The Poms probably have been furiously tapping all of the EU govts phones and networks for the last 3 years (BREXIT) and the French and Germans since the telegraph and phone were invented. All govts have secret ops going that would be highly embarrassing if details ever saw the light of day.
